ReconOperatorCompFilter

public ReconOperatorCompFilter(ReconInfo reconInfo,
                               DataSet dataSet,
                               java.lang.String operator,
                               int precedence)

Any comparison filter operator

Parameters:

operator -

Method Detail

getInstance

public ReconOperator getInstance()

Description copied from class: ReconOperator

Factory-like method to allow operator objects that cache initializations to return a new instance instead of this

Specified by:

getInstance in class ReconOperator

Returns:

overrides will return a new instance

getObjectName

public java.lang.String getObjectName()

initialize

protected void initialize(java.lang.String fullyQualifiedName,
                          java.lang.String value,
                          ComparisonQueryHelper qh)

evaluateOperator

                                       ComparisonQueryHelper qh)

Parameters:

attribute - the attribute name to be compared, in form of object.attribute (both lowercase)

value - the value against which the attribute is compared

allStatements - a HashMap keyed on lower case object names, contains ComparisonStatement objects

Returns:

a list of the ReconValue objects that satisfied the condition
